marcus.io · Making RSS more visible again with a /feeds page

Personal website owners – what do you think about collecting all of the feeds you are producing in one way or the other on a /feeds page?

Sounds like a good idea! I’ll get on that.

Why I hate the log graph, and you should too - Geek in Sydney

I must admit I’ve been wincing a little every time I see a graph with a logarithmic scale in a news article about COVID-19. It takes quite a bit of cognitive work to translate to a linear scale and get the real story.

SofaConf 2020 - a technical write-up | Trys Mudford

Trys describes the backend architecture of the excellent Sofa Conf website. In short, it’s a Jamstack dream: all of the convenience and familiarity of using a database-driven CMS (Craft), combined with all the speed and resilience of using a static site generator (Eleventy).

I love the fact that anyone on the Clearleft events team can push to production with a Slack message.

I also love that the site is Lighthousetastically fast.

Reading

At the beginning of the year, Remy wrote about extracting Goodreads metadata so he could create his end-of-year reading list. More recently, Mark Llobrera wrote about how he created a visualisation of his reading history. In his case, he’s using JSON to store the information.

This kind of JSON storage is exactly what Tom Critchlow proposes in his post, Library JSON - A Proposal for a Decentralized Goodreads:

Thinking through building some kind of “web of books” I realized that we could use something similar to RSS to build a kind of decentralized GoodReads powered by indie sites and an underlying easy to parse format.

His proposal looks kind of similar to what Mark came up with. There’s a title, an author, an image, and some kind of date for when you started and/or finished reading the book.

Matt then points out that RSS gets close to the data format being suggested and asks how about using RSS?:

Rather than inventing a new format, my suggestion is that this is RSS plus an extension to deal with books. This is analogous to how the podcast feeds are specified: they are RSS plus custom tags.

Like Matt, I’m in favour of re-using existing wheels rather than inventing new ones, mostly to avoid a 927 situation.

But all of these proposals—whether JSON or RSS—involve the creation of a separate file, and yet the information is originally published in HTML. Along the lines of Matt’s idea, I could imagine extending the h-entry collection of class names to allow for books (or films, or other media). It already handles images (with u-photo). I think the missing fields are the date-related ones: when you start and finish reading. Those fields are present in a different microformat, h-event in the form of dt-start and dt-end. Maybe they could be combined:


<article class="h-entry h-event h-review">
<h1 class="p-name p-item">Book title</h1>
<img class="u-photo" src="image.jpg" alt="Book cover.">
<p class="p-summary h-card">Book author</p>
<time class="dt-start" datetime="YYYY-MM-DD">Start date</time>
<time class="dt-end" datetime="YYYY-MM-DD">End date</time>
<div class="e-content">Remarks</div>
<data class="p-rating" value="5">★★★★★</data>
<time class="dt-published" datetime="YYYY-MM-DDThh:mm">Date of this post</time>
</article>

That markup is simultaneously a post (h-entry) and an event (h-event) and you can even throw in h-card for the book author (as well as h-review if you like to rate the books you read). It can be converted to RSS and also converted to .ics for calendars—those parsers are already out there. It’s ready for aggregation and it’s ready for visualisation.

I publish very minimal reading posts here on adactio.com. What little data is there isn’t very structured—I don’t even separate the book title from the author. But maybe I’ll have a little play around with turning these h-entries into combined h-entry/event posts.

The Cost of Javascript Frameworks - Web Performance Consulting | TimKadlec.com

Excellent in-depth research by Tim on how the major frameworks affect performance. There are some surprising (and some unsurprising) findings in here.

I wish with all my heart that this data would have some effect but I fear there’s an entire culture of “modern” web development that stick its fingers in its ears and say “La, la, la, I can’t hear you.”

80 geocoding service plans to choose from.

I’m going to squirrel this one away for later—I’ve had to switch geocoding providers in the past, so I have a feeling that this could come in handy.

Local-first software: You own your data, in spite of the cloud

The cloud gives us collaboration, but old-fashioned apps give us ownership. Can’t we have the best of both worlds?

We would like both the convenient cross-device access and real-time collaboration provided by cloud apps, and also the personal ownership of your own data embodied by “old-fashioned” software.

This is a very in-depth look at the mindset and the challenges involved in building truly local-first software—something that Tantek has also been thinking about.

Accessible HTML Elements | Amber’s Website

Amber runs through some HTML elements that help you provide semantic information—and accessibility—for your website: headings, paragraphs, lists, and more:

You may be aware that ARIA roles are often used with HTML elements. I haven’t written about them here, as it’s good to see how HTML written without ARIA can still be accessible.

Adding Response Metadata to Cache API Explainer by Aaron Gustafson and Jungkee Song

This is a great proposal that would make the Cache API even more powerful by adding metadata to cached items, like when it was cached, how big it is, and how many times it’s been retrieved.

99 Good News Stories You Probably Didn’t Hear About in 2019

The goal in putting these stories together has never been to create a warm glow, or lull anyone into a false sense of complacency. The challenges facing the human family right now are big and scary and there’s no guarantee we will overcome them.

As millions of people have demonstrated in the past 12 months though, action is possible, better solutions are available and a better future can be built.
